ABOUT DKIM RECORD CHECK

DKIM Wizard DKIM Wizard This wizard will allow you to easily create a public and private key pair to be used for DomainKeys and DKIM signing within PowerMTA™. The key pair will be used for both DomainKeys and DKIM signing.Policy records are no longer included as they are part of the deprecated DomainKeys, and not DKIM. FREE DKIM Wizard Domain Key Generator Use this FREE DKIM Wizard and domain key generator to create a dns TXT record and 1024-bit or 2048-bit private and public keys for email header authentication. The public key is entered into your DNS and your private. DKIM lets you add a digital signature to outbound email messages in the message header. It may sound complicated, but it's really not. When you configure DKIM, you authorize your domain to associate, or sign, its name to an email message by using cryptographic authentication. DKIM Core Tools Generate a DKIM Core Key. Domain name: Enter the domain you'd like to generate keys for, for example dkimcore.org and hit the button. If you're thinking of using these keys in production, you should check the security notes first. Check a published DKIM Core Key.

The DKIM Check tool will perform a DKIM record test against a domain name and selector for a valid published DKIM key record. DomainKeys Identified Mail (DKIM) defines a domain-level digital signature authentication framework for email by permitting a signing domain to assert responsibility for a message in transit. DKIM authenticates the reputation and identity of the email sender and their email signing practices for additional handling (i.e. does email get delivered, quarantined, or rejected). DKIM authentication of a message is validated via a cryptographic signature and querying the signer’s domain to retrieve a public key. This tool tests the ability to retrieve the DKIM public key using a domain and a selector.

How to Use the DKIM Check Tool: There are two (2) ways to test a DKIM record with the DKIM Record Checker. The first is just using a domain and selector separated by a colon and the second option is using the host/name format of the record.

  • Option 1: (domain):(selector) i.e. mxtoolbox.com:email - where mxtoolbox.com is the domain part and email is the selector, separated by a colon
  • Option 2: (selector).(_domainkey).(domain) i.e. email._domainkey.mxtoolbox.com - where email is the selector followed by ._domainkey. and then mxtoolbox.com as the domain. Note: If you use this method, you will input all of this into the Domain Name input field and leave the Selector field empty.

What is a DKIM Selector? A DKIM selector is text that is added with the domain to create a unique DNS record used during DKIM. This allows multiple keys to exist under one domain which allows for different signatures to be created by different systems, date ranges, or third party services.

Now you can quickly view your DomainKeys, DKIM, and SPF validity, and SpamAssassin score in one place.Just send an email to any address @dkimvalidator.com. Then check here to see the results.

Here is a random address that you can use:

This is useful for verifying the end-to-end functionality of your DKIM and SPF configuration,as well as your actual SpamAssasin score. Since your email is sent through regular mail servers,all of the headers that these tools see are the same as your email recipients will see.

Configuring DKIM from scratch is difficult since it involves changes to your DNS configuration.DNS records are heaviliy cached, so making changes to the DNS configuration often involves waitingfor hours between each test. This tool attempts to look up DKIM records directly from yourauthoritative server on each tests as a way to try to minimize that delay.

A few quick notes about how this works:

Dkim Wizard Vs

  • Messages sent to any @dkimvalidator.com address are routed to our Mandrill Inbound mail account
  • Mandrill submits the email messages to our server where it is saved for the other tools to read
  • We use the Perl Mail::DKIM::Verifier package to display DKIM information
  • We use the Perl Mail::SPF package for information about SPF validity
  • We use the Perl Mail::SpamAssassin package for SpamAssassin results
  • We use the Perl Net::DNS::Resolver::Programmable for some more detailed DNS Lookups

Dkim Wizard Spell

Our SpamAssassin is just a vanilla installation with nothing extra installed.sa-update is run dailyso that the SpamAssassin rules should always be current.

It will accept messages sent to anything @dkimvalidator.com. Messages will be deleted a few hoursafter they are received. The message is saved once, and the tests are performed each time you loadthe page. This gives you the opportunity to change your DNS records and check the message againwithout having to resend the message. We try to lookup DKIM and SPF records directly from theauthoritative servers whenever possible.
